AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DODGE CITY KS
402 PM CDT SUN OCT 12 2014

...UPDATE TO LONG TERM...

.SHORT TERM...(THIS EVENING THROUGH MONDAY)
ISSUED AT 335 PM CDT SUN OCT 12 2014

ISOLATED THUNDERSTORMS DEVELOPED IN AN AREA OF SURFACE CONVERGENCE
AND 1000 J/KG MOST UNSTABLE CAPES VALUES WEST OF ELKHART, AND WERE
SPREADING EAST AND BECOMING MORE MULTICELLULAR WITH TIME. THOSE
STORMS GREATEST SEVERE POTENTIAL  WILL BE A WIND THREAT OVER THE NEXT
COUPLE OF HOURS, AS A COLD FRONT WILL SLOWLY OVERTAKE THE AREA THIS
EVENING. ADDITIONALLY, MORE NUMEROUS SHOWERS AND SCATTERED STORMS
WILL THEN MOVE ACROSS THE AREA OVERNIGHT NEAR THE POCKET OF THE MID
LEVEL COLD POOL ROTATING OUT OF COLORADO. THE NAM MODEL POPS WERE
FOLLOWED FOR THIS PRECIPITATION  EPISODE RANGING FROM 60 TO 90 PERCENT
CHANCES FOR RAIN. THE FRONTOGENETIC SIGNAL WILL INTERCEPT HIGH MEAN
LAYER MOISTURE VALUES IN CENTRAL KANSAS WHERE THE BEST RAINS SHOULD
FALL BETWEEN MIDNIGHT AND EARLY MONDAY MORNING IN THE DEFORMATION
ZONE.

ADDITIONALLY, SURFACE WIND SPEEDS BEHIND THIS COLD FRONT SHOULD
BECOME PROBLEMATIC AT LEAST BY MONDAY MORNING. SOME OF THE GUIDANCE
AND MODEL OUTPUT INDICATES AN ISALLOBARIC RISE BEHIND THE INITIAL
COLD FRONT WITH STRONG WIND AROUND MIDNIGHT TONIGHT. HOWEVER THE MORE
SIGNIFICANT OPPORTUNITY FOR STRONG WINDS WILL BE AS THE SURFACE
GRADIENT BECOMES STRENTHENED LATE MONDAY MORNING AND INSOLATION
CREATES DEEPLY STEEP LAPSE RATES FOR MIXING OF THE 850 MB JET IN THE
WEST. GUSTS MIGHT NOT BE AS BIG OF AN ISSUE AS SUSTAINED 30 TO NEAR
35 KNOT WIND SPEEDS THROUGH THE HIGHWAY 83 CORRIDOR. A WIND ADVISORY
HAS BEEN HOISTED FOR TONIGHT FOR THE WESTERN HALF OF THE FORECAST
AREA, AND EXTENDED FOR THE ENTIRE AREA THROUGH THE DAY ON MONDAY.

.LONG TERM...(MONDAY NIGHT THROUGH SUNDAY)
ISSUED AT 357 PM CDT SUN OCT 12 2014

MEDIUM RANGE MODELS INDICATE A DEEP UPPER LEVEL TROUGH OF LOW
PRESSURE SHIFTING EASTWARD ACROSS THE CENTRAL PLAINS TUESDAY.
MEANWHILE, BUILDING UPPER LEVEL RIDGING IS PROJECTED TO DRIFT
EASTWARD ACROSS THE INTERMOUNTAIN WEST INTO THE WESTERN HIGH
PLAINS. ALONG WITH A WEAKENING FLOW ALOFT AND MUCH DRIER AIR
FILTERING SOUTHWARD INTO WESTERN KANSAS, NO PRECIP IS EXPECTED
ACROSS THE REGION EARLY IN THE PERIOD. DRIER CONDITIONS ARE
EXPECTED TO CONTINUE THROUGH THE END OF THE WEEK AS THE UPPER
LEVEL RIDGING MOVES SLOWLY EAST ACROSS THE WESTERN HIGH PLAINS.

WARMER TEMPERATURES ARE LIKELY FROM MONDAY INTO TUESDAY AS THE
COLDER AIR MASS ACROSS THE WESTERN HIGH PLAINS BEGINS TO SLOWLY
ERODE. THE GFS AND ECMWF SHOW H85 TEMPERATURES CLIMBING INTO THE
LOWER TEENS(C) ACROSS CENTRAL KANSAS TO THE UPPER TEENS(C) CLOSER
TO THE COLORADO BORDER. UNDER MOSTLY CLEAR SKIES, LOOK FOR HIGHS
GENERALLY UP INTO THE LOWER TO MID 70S(F) TUESDAY AFTERNOON. A
STRENGTHENING LEE SIDE TROUGH WILL ENHANCE WARM AIR ADVECTION INTO
WESTERN KANSAS WEDNESDAY PUSHING HIGHS WELL UP INTO THE MID TO
UPPER 70S(F) WITH THE LOWER 80S(F) LIKELY ACROSS EXTREME SOUTHWEST
KANSAS. THE WARMING TREND WILL LEVEL OFF THURSDAY AS ANOTHER COLD
FRONT IS EXPECTED TO PUSH SOUTHWARD ACROSS WESTERN KANSAS.

&&

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z MONDAY AFTERNOON)
ISSUED AT 137 PM CDT SUN OCT 12 2014

BROKEN TO WIDESPREAD MID LEVEL COUDINESS MAY LIMIT THE SEVERE
POTENTIAL FOR THIS EVENING. REGARDLESS, THE CHANCES FOR SHOWERS AND
RAIN WILL BE INCREASING AS A COLD FRONT MOVES INTO THE AREA THROUGH
03 UTC. SURFACE GRADIENT WINDS WILL INCREASE BEHIND THE BOUNDARY AS
WELL AROUND MIDNIGHT TO THE 23 TO 27 KNOT RANGE. ONCE THE UPPER
TROUGH TRAVERSES THE REGION, INSOLATION WILL AID THE SURFACE
GRADIENTS WINDS THROUGH MIXING TO DRIVE SUSTAINED WINDS AT GCK TO
NEAR 35 KNOTS BRIEFLY AROUND 18 UTC MONDAY.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF CENTRAL...SOUTH
CENTRAL...SOUTHWEST AND WEST CENTRAL KANSAS.

.DAY ONE...TODAY AND TONIGHT

SHOWERS AND THUNDERSTORMS WILL DEVELOP STARTING IN EASTERN COLORADO
DURING THE AFTERNOON AND THEN WILL SPREAD ACROSS SOUTHWEST KANSAS THROUGH
THE EVENING. THE BEST CHANCE FOR MORE ORGANIZED SEVERE THUNDERSTORMS
IS ALONG AND SOUTH OF A LINE FROM SYRACUSE TO DODGE CITY TO SAINT JOHN.
HERE, THE MAIN THREATS ARE HAIL UP TO THE SIZE OF QUARTERS, 60 MPH
THUNDERSTORM OUTFLOW WINDS, AND LIGHTNING. HEAVY RAINFALL IS ANOTHER
THREAT LATER THIS EVENING ACROSS SOUTH CENTRAL KANSAS. NORTH OF THE
AFOREMENTIONED LINE, THE THUNDERSTORMS ARE EXPECTED TO BE LESS ORGANIZED
AND THEREFORE LESS SEVERE.

BEHIND A PASSING COLD FRONT LATE THIS EVENING INTO MONDAY, STRONG NORTH-
NORTHWESTERLY WINDS OF 25 MPH TO 35 MPH ARE EXPECTED.

.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY

THE STRONG NORTH-NORTHWESTERLY WINDS OF 25 MPH TO 35 MPH WILL CONTINUE
THROUGH MUCH OF THE DAY ON MONDAY.

OTHERWISE, THE PROBABILITY OF HAZARDOUS WEATHER IS LOW FOR THE REST
OF THE PERIOD.
